PRINCETON BOROUGH – Princeton High has won its way into a doubleheader Friday at the NJSIAA Central B swimming finals at North Brunswick High.

A day after the boys took care of Freehold Borough, the Princeton girls followed suit, dispatching Lawrence 107-63 in the sectional semifinal.

Princeton’s boys will get things started Friday at 4 p.m. against Ocean Township, followed by the Princeton girls at 6 p.m. against Manasquan, a 102-68 winner over Rumson-Fair Haven yesterday.

It was Manasquan that the Princeton girls (11-0) defeated 90-80 in last year’s sectional final after knocking off Rumson-Fair Haven in the semis. With the last meeting so recent, Princeton coach Greg Hand remembers Manasquan well.

“Manasquan has very fast sprint freestyle team and I know that they can certainly hold their own in the strokes too,” Hand said. “I think that they’re formidable. The Power Points are close enough that there’s no basis for making any prediction score-wise. It’s a challenging matchup for us.”

Hand’s team put Lawrence away early yesterday, just as the Tigers had done in a 119-51 dual-meet victory back in December.

Heading into the 200-yard freestyle relay, Princeton led 75-35 and had taken first place in five of seven events. The only events a Tiger swimmer didn’t win, Lawrence’s Kate O’Rourke claimed when she took the 50 free and 100 free.

Though Princeton may have owned the final score, especially early on before Hand scratched his top teams from the last two relay events, O’Rourke’s victories were no fluke. The freshman was a runner-up in the 50 free at the Mercer County meet earlier this month, half a second behind eventual Most Valuable Swimmer honoree Jocelyn Yuen of West Windsor-Plainsboro South.

Yesterday, O’Rourke was nearly two seconds in front of Princeton’s Meryl Stone for 50 free gold, and she finished more than two seconds ahead of Stone in the 100 free.

Lawrence (6-6) won two of the last four events, with O’Rourke anchoring a victory in the 200 free relay and Caitlin Lavery winning the breaststroke.

Jennifer Enos, in the 200 free and 500 free, and Marisa Giglio, in the 200 IM and backstroke, were two-time winners for Princeton.

Giglio was also a two-time winner for the Tigers in last season’s sectional final against Manasquan, as were Serena Deardorff, who won the butterfly yesterday, and Victoria Cassidy. Though Princeton retains Giglio and Deardorff, Cassidy has traded in her Princeton blue for University of Maryland red.

“We still have a lot of fast kids, but Victoria (Cassidy) was probably a more guaranteed two wins than we’ve ever had since Nina Rossi,” Hand said, referring to the 2006 Princeton High alumna who also went to Maryland. “Though a couple of our younger kids are moving in that direction.”

Princeton’s wait to take another step in that direction is down to just two days.
